We detected concentrations of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCs) in the liver, muscle, and fat of 11 loggerhead sea turtles Caretta caretta from the central and southern Adriatic Sea. All samples contained PCBs at various concentrations, with Congener 138 (28%), 153 (27%), and 180 (32%) dominating the congener composition of the tissues. The dioxin-like congener (118, 13%) was detected in all tissues analyzed. The lower-chlorinated PCBs were not detected. The average of the total PCB concentrations, expressed in nanograms per gram wet weight, was 459.6 ng g(-1) in fat, 82.9 ng g(-1) in liver, and 5.8 ng g(-1) in muscle. Among 13 organochlorine pesticides for which analyses were conducted, 4 were detected: p,p'-DDE (57%); p,p'-DDD (16%); and p,p'-DDT and o,p'-DDT (27%). Spatial differences were found among OC concentrations in loggerheads from the central and southern Adriatic Sea. The only samples containing detectable concentrations of p,p'-DDT and o,p'-DDT were from the southern area.
我们检测了来自亚得里亚海中部和南部的11只蠵龟（Caretta caretta）肝脏、肌肉和脂肪中的多氯联苯（PCBs）和有机氯农药（OCs）浓度。所有样本均含有不同浓度的多氯联苯，其中同系物138（28%）、153（27%）和180（32%）在组织的同系物组成中占主导地位。在所有分析的组织中均检测到了类二噁英同系物（118，13%）。未检测到低氯代多氯联苯。以每克湿重纳克表示的多氯联苯总浓度平均值在脂肪中为459.6 ng g(-1)，在肝脏中为82.9 ng g(-1)，在肌肉中为5.8 ng g(-1)。在所分析的13种有机氯农药中，检测到了4种：p,p'-滴滴伊（57%）；p,p'-滴滴滴（16%）；以及p,p'-滴滴涕和o,p'-滴滴涕（27%）。在亚得里亚海中部和南部蠵龟的有机氯浓度之间发现了空间差异。唯一含有可检测浓度的p,p'-滴滴涕和o,p'-滴滴涕的样本来自南部地区。
